in a slide of Gamboge, mounted in August, 1866. Mr. G. E. Davis replied 
by giving a summary of what had been read in a paper before the Royal 
Microscopical Society. Mr. Chadwick and the President also took part in the 
discussion, 
Mr. George E. Davis, F.R.M.S., one of the vice-presidents, then read a 
valuable and interesting paper on Photo-Micrography, which was _ illustrated 
by numerous photo-micrographs, glass crystals, Avachnotdiscus Ehrenbergit, 
Gyrosigma attenuatum, Peronospora infestans, and a section of coniferous wood 
(Pinus pinaster), all photographed with the quarter-inch objective ; a glass 
crystal and the cuticle of Esparto Grass ( Macrochloa tenacissima), taken with 
the one-eighth-inch objective ; and several others taken with the half and one 
inch, Mr. Davis also took an enlarged picture of the proboscis of a blow fly 
before the members to further illustrate his paper. 
After the reading of the paper, a discussion followed, and information on 
various points was elicited from the Lecturer; Messrs. Doherty, Blackburn, 
Hall, Dearden, and Cook, took part. The meeting then resolved itself into a 
conversazione, when various and interesting objects were exhibited by many of 
the members by means of their*microscopes. The following gentlemen 
assisted, and during the evening were shewn :—

MANCHESTER MICROSCOPICAL SOCIETY ANNUAL SOIREE, — 
The annual soirée of the Manchester Microscopical Society took place in the 
Lecture Hall of the Athenzeum, on Saturday evening, February 26th. The 
members exhibited, by means of microscopes, which were placed on tables, 
arranged around the room, a variety of objects illustrative of pond life, and 
other branches of the animal and vegetable world, as well as preparations from 
the mineral kingdom. There were present a large number of members and 
friends. During the evening the Rev. J. G. Wood, M.A., delivered a lecture 
on Unappreciated Insects. 
Mr. Wood said the subject was a wide one, because he did not believe any 
insect was really appreciated. Appreciation depended entirely upon knowledge. 
He believed it was an absolute fact that there was no insect, however insig- 
nificant it might appear, or however noxious we might think it, which was not 
directly or indirectly a benefactor to mankind. He should choose one or two 
of the commonest of our British insects, which we are apt to call noxious because 
we do not understand them, and having succeeded in showing that they serve 
to prepare the earth for the existence of man, he thought it would be fair to 
conclude that the same was the case with the whole of the insect tribes. He 
would select an insect which is well known to many of us, and is not
